I have not tried to do the stiletto shape with popits but i don't imagine it would work well really,
if you are talking about doing it with a tip you would gets lots of product under the free edge when you place the popit,
if you were thinking of using just the popit in a sculpting fashion it would be fiddly and need a lot of filing to get the stiletto shape,
as i say i have not tried to do the stiletto shape with popits so this is just my guessing as to what would happen,
i have used them for square nails on clients,
and i always wear my nails in the stiletto shape but shaped with the brush not popits, hth :hug:
